Kirby 30 vs Mirage 25: the short version
- The Kirby 30 is the larger boat at 29.7 ft9.04 m LOA versus 25.2 ft7.67 m for the Mirage 25.
- The Kirby 30 is heavier, displacing about 22% more, which usually means a steadier but slower-to-accelerate hull.
- The Mirage 25 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the Mirage 25 rates better for offshore work (2.32 vs 2.34).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
